Abstract

The utility model discloses a cleaning-free smoke exhauster. The cleaning-free smoke exhauster comprises an air collection hood, a changing-over pipe and a flue pipe, wherein the changing-over pipe is arranged between the flue pipe and the air collection hood; the smoke collection hood comprises an outer wall hood and an inner wall hood; an air pipeline is formed between the outer wall hood and the inner wall hood; the air pipeline comprises a circumferential skew wind air inlet pipeline and a circumferential vertical wind air inlet pipeline, both of which hare respectively connected with an air blower; the vertical wind air inlet pipeline is arranged in the changing-over pipe; the skew wind air inlet pipeline is arranged at the lower end of the vertical wind air inlet pipeline; the terminal end of the circumferential wind outlet of the skew wind air inlet pipeline is bent towards the inner side of the air collection hood; and the terminal end of the circumferential air outlet of the vertical wind air inlet pipeline is vertically and upwards bent towards the inner side of the changing-over pipe. The cleaning-free smoke exhauster, disclosed by the utility model, has the advantages of overcoming defects caused by that cooking fumes and waste gas must be exhausted by vanes of a fan in the prior art, not only solving the pollution problem in a kitchen, but also lightening labor intensity of people, and being clean and sanitary, convenient to use and simple in structure.

Description

A kind of disposable smoke exhaust

Technical field

The utility model relates to a kind of lampblack absorber, relates in particular to a kind of disposable smoke exhaust.

Background technology

Chinese eating habit is the cooking of eating various tastes, when cooking, say that generally iron pan burns awfully hotly, moment in oil being poured into pot, oil can be smoldered at once, or the dish that wish is fried is put in rusting when smoldering again, and at this moment oil smoke can be larger, most of by fume exhausting fan suction flue, discharge outdoor.Limited because of the draft of fume exhausting fan, oil smoke can not in time be taken away, and high-temperature oil smoke is met cold and become liquid, be attached on smoke pumping cover wall or the walling of flue, hot gas is roasting when being cooked again becomes again oily vapour and is diffused in the kitchen, causes environmental pollution, is detrimental to health.

The existing smoke exhaust that uses is divided into flat-back type, side-suction type, deep suction type etc., no matter but be any pattern, all be directly to discharge through the fan blade of the blower fan in the changing-over pipe with oil flue waste gas, water vapour, make the fan blade of blower fan be stained with inevitably tar, need often to clean, quite feeling loaded down with trivial details, also is to make the blower fan easy break-down simultaneously, has greatly shortened the service life of blower fan.

The utility model content

The purpose of this utility model is to provide a kind of disposable smoke exhaust, does not have the fan blade of blower fan in the changing-over pipe of this disposable smoke exhaust, simple in structure, clean hygiene, easy to use, and smoke pumping speed is fast.

To achieve these goals, the technical solution of the utility model is: a kind of disposable smoke exhaust is provided, comprise gas skirt, changing-over pipe and flue tube, the changing-over pipe is located between flue tube and the gas skirt, wherein, gas skirt comprises outer wall cover and inwall cover, form feed channel between described outer wall cover and the inwall cover, feed channel comprises circumferential skew wind admission line and circumferential vertically-supplying air admission line, the skew wind admission line links to each other with air blast respectively with the vertically-supplying air admission line, the vertically-supplying air admission line is located in the changing-over pipe, the skew wind admission line is located at the lower end of vertically-supplying air admission line, the circumferential air outlet end of skew wind admission line lateral buckling in the gas skirt, the circumferential air outlet end of vertically-supplying air admission line is to the inboard upwards vertical bending of changing-over pipe.

Described air blast quantity is two, and one of them air blast air feed is to the skew wind admission line, and another air blast air feed is to the vertically-supplying air admission line.

Described two air blasts all are located at the gas skirt outer surface.

The disposable smoke exhaust of the utility model overcomes oil flue waste gas in the prior art must discharge the defective of bringing through impeller of blower, has not only solved the pollution problem in kitchen, more can alleviate people's labour intensity, and clean hygiene is easy to use, simple in structure.

Description of drawings

Fig. 1 is the sectional structure schematic diagram of the disposable smoke exhaust of the utility model;

Fig. 2 is the plan structure schematic diagram at A-A place among Fig. 1;

Among the figure: 1, flue tube; 2, gas skirt; 3, outer wall cover; 4, inwall cover; 5, air blast; 6, air blast; 7, skew wind admission line; 8, vertically-supplying air admission line; 9, outer wall cover; 10, changing-over pipe.

The specific embodiment

For the technology contents that describes the disposable smoke exhaust of the utility model in detail, structural feature, below in conjunction with embodiment and cooperate accompanying drawing to be described further.

Such as Fig. 1, shown in 2, the disposable smoke exhaust of the utility model, comprise gas skirt 2, changing-over pipe 10 and flue tube 1, changing-over pipe 10 is located between flue tube 1 and the gas skirt 2, wherein, gas skirt 2 comprises outer wall cover 3 and inwall cover 4, described outer wall cover 3, form feed channel between outer wall cover 9 and the inwall cover 4, feed channel comprises circumferential skew wind admission line 7 and circumferential vertically-supplying air admission line 8, skew wind admission line 7 is connected with air blast 5, vertically-supplying air admission line 8 is connected with air blast 6, vertically-supplying air admission line 8 reaches in the changing-over pipe 10 from the gas skirt extension, skew wind admission line 7 is located at the lower end of vertically-supplying air admission line 8, the circumferential air outlet end of skew wind admission line 7 lateral buckling in the gas skirt, and the circumferential air outlet end of vertically-supplying air admission line 8 is to the inboard upwards vertical bending of changing-over pipe.

Described air blast quantity is two, and wherein air blast 5 air feeds are to skew wind admission line 7, and another air blast 6 air feeds are to vertically-supplying air admission line 8.Described two air blasts all are located at the gas skirt outer surface.Skew wind admission line 7 and vertically-supplying air admission line 8 are circumferential cover body.

The wind of described air blast 5 blows side in skew wind admission line 7 oblique gas skirts, shown in the oblique arrow among Fig. 1, the wind of air blast 6 from vertically-supplying air admission line 8 vertically to the scavenge trunk inboard to blowing up, shown in the vertical arrows among Fig. 1, therefore form high negative pressure in the gas skirt, therefore discharge the oil smoke water vapour outdoor from flue tube fast.

Above disclosed only is preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
